The correct answer is GnRH
GnRH is the acronym for gonadotropin-releasing
hormone. It is released in the brain by the hypothalamus, after which it
gives signals to the pituitary gland to release the gonadotropin hormones (GH);
luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

Sweating happens when your body gets too hot. Sweating is very effective because if your body didn’t have the ability to cool itself down you could get faint and disoriented from too much heat intake
Answer:
signal molecule is a general term for molecules also called (ligands)that bind specifically to other molecules (such as receptors). hope it helps!!
Answer:The above statement is "false".
Explanation:
The following events take place during contraction-relaxation of a muscle:
•Action potential in T tubule activates voltage-sensitive receptors,which in turn trigger Ca ions release from terminal cisternae of sacroplasmic reticulum(SR) into cystol.
•Ca ions bind to troponin;troponin changes shape,removing the blocking action of tropomyosin;actin active sites is exposed.
•CONTRACTION; myosin heads alternatively attach to actin and detach,pulling the actin filaments toward the center of the sarcomere;using ATP in this process.
•removal of Ca ions by active transport into the SR after the action potential ends.
•RELAXATION occurs.Actin and myosin return back to its unbound state.
